2006 GT Charging System Problems?
I was wondering if yall could help me figure out what is going on with my car.
A few months ago my battery went dead so I replaced it and then my "check charging system" light came on. I drove it for about a month till my dad came to town and looked at it. We took the alternator off and had it test...it was bad. So i got a new alternator and put it on. It was fine for about a week. Then the light came back on.
When it first started coming on, before I replaced the alternator, it wouldn't come on till the car started heating up and it would stay on the go off but then pop back up a few minutes later.
This time it comes on every morning, but goes off once the car starts heating up and doesnt come on for the rest of the day. I have also noticed that a few minutes after cranking it, the ac/ heater will go in and out ( not all the way out, just stop blowing as hard), the lights will dim and then go to normal brightness, and the RPMs will go up and down. I think it stops that when it is fully warmed up. (The ac/heater, lights, and RPM things all happen throughout the day)
